I'm going to transfer some filter media balls from my Eheim (external canister wet/dry) to my internal fluval in my QT
1. Eheim say you've got to put on a foam cover over the filter intake for the first 6 weeks, until cycling etc. has finished. The 6 weeks is now up - will taking this foam off the intake, AND in the same day removing some of the filter balls cause any problems with my main tank? I also have 2" live sand and quite a bit of rock (which should be live by now), and levels are all ok and have remained totally stable.
2. Will there be enough bacteria on the balls that I'm putting in my fluval (which at the moment has normal foam pads in it, I'm going to replace the foam pads with the eheim balls) so that I won't get any amm/nit spikes when I put my fish in QT
3. When transferring the balls across, there are 2 baskets of them in the Eheim. How long can the balls be exposed to air, and out of the water, before the bacteria die? Is it ok to get a handful out with my hand, or would you use some sort of utensil to get the balls out and transfer them across?
4. Assuming my fish is ok in QT
, and I don't use any medications, would putting some new, fresh media balls (and adding them to the ones that are already there) back in the eheim in my main tank, be preferable to putting the balls BACK that have been in the fluval?
